What equipment do you need to process onions?

1. Onion root cutting machine & Onion peeling machine

Workers peel onions and cut roots, which is very slow and easily irritates the eyes, which is a pain point. How can farmers ensure efficiency while making workers happy at work?

Let me introduce the onion root cutting machine and onion peeling machine.

  • The onion root cutter is mainly designed to cut off the roots of onions. The high-speed rotating blade inside cuts off the roots of the onions one by one. The onions are transported to the onion peeling machine through the conveyor belt.

  • The onion peeling machine mainly uses compressed air as a power source to blow away the onion skin through the swirling airflow. The dry onion skin will be blown away. The whole process does not require soaking in water or cutting with a knife, and the onions will not be worn. The airflow is used for dry peeling to ensure the integrity of the onions.

2. Air Bubble Cleaning Machine

After peeling, the onion skin will be stained with dust, etc. 

  • The bubbling cleaning machine can remove the dust on the onion skin, and the onion skin that is stained can be cleaned through this process. The clean onions are transported to the next process via a conveyor belt: dicing and slicing.

    Onion cutting equipment is multifunctional and can meet different needs of customers.

4. Lifting conveyor

The lifting conveyor serves as a connection between the front-end and back-end equipment.

5. Multi-head weighing packaging machine

  • In order to avoid contamination, processed onions are packed in bags. This can reduce the contact between onions and air. The automatic weighing and packaging machine not only realizes the weighing function, but also the packaging function, which improves production efficiency.

Which markets can you sell processed onions to?

  • Large supermarket.

 Many large supermarkets offer different types of onions. Diced onions, sliced onions, and raw onions. Customers can buy processed onions and cook directly with them when they get home.

  • Chain restaurants.

 Many large chain restaurants will buy processed vegetables. Because this can save time and energy. Nowadays, the pace of social life is very fast, and time is business.

  • Small restaurants and breakfast shops.

 Many small restaurants also need processed onions and other vegetables.

  • Schools, prisons and other places where people gather.

The cost of peeling and processing onions into production lines and packaging methods

The cost of onion processing production line will vary according to the buyer's output. So the specific cost still needs to be discussed with the supplier. Most small-volume production lines may require a 20HQ container for loading. There are also some large-scale onion peeling production lines that will require a 40HQ container for loading after packaging in wooden boxes.

Production Lead Time and Voltage Issues of Onion Peeling Production Line

  • The production cycle of a small-scale 300KG/H onion processing line is generally 20 days. The production cycle of a large-scale 400-600KG/H onion peeling processing line is 30 days.

  • Regarding voltage issues, the factory generally provides voltage change services. When it comes to voltage change, the factory will customize the motor from the motor manufacturer in advance, including electrical components, etc.

  • Most onion peeling and processing lines use three-phase industrial voltage. For example: 440V 3ph | 380V 3ph, etc.

Onion Processing Equipment, How to Maintain?

Onion root cutting machines, onion peeling machines, and onion slicers are all related to food, so many of the materials of the machines are 304 stainless steel, which meets food safety levels.

  • Since the machine is composed of many parts, many bearings need to be lubricated every half a month.

  • The operation and shutdown of the machine should be done according to the steps. The emergency stop switch cannot be used as a one-button switch, otherwise it will cause damage to the circuit components of the machine.

  • For onion cutting equipment, clean the remaining vegetable juice with clean water after each day's work to prevent the blade from becoming blunt later.

  • The onion peeling equipment should be cleaned daily with an air gun to avoid a lot of dust inside.
